Diamondbacks GM Dave Stewart told reporters (including Zach Buchanan of azcentral.com) that Blue Jays catcher Dioner Navarro or Tigers catcher Alex Avila could be fits for his team in their search for help behind the plate, while the Snakes have no interest in Geovany Soto. Stewart said his team doesn’t intend to trade relief pitching to obtain a catcher, however.

The Rockies are receiving “massive interest” in Corey Dickerson, FOX Sports’ Ken Rosenthal reports (via Twitter). Despite all this interest, Colorado would have to get an overwhelming offer to deal the outfielder.

Also from Rosenthal, it’s been nothing but “crickets” for the Rockies on interest in Troy Tulowitzki.

Here are the latest pieces of information on the trade front from the morning’s action at the Winter Meetings:

The Rockies approached the Mets today to gauge interest in discussing star shortstop Troy Tulowitzki, Andy Martino of the New York Daily News reports on Twitter. Martino’s sources tell him a deal that would send Tulowitzki to the Mets is “not happening.” On the other hand, Colorado’s actions obviously suggest that there is at least some possibility that the club would consider dealing him.

The Phillies would not demand that the Red Sox include top catching prospect Blake Swihart in a deal involving Cole Hamels, Gordon Edes of ESPNBoston.com reports on Twitter.

Were the Red Sox to make a push for Jeff Samardzija, however, the Athletics would insist on the inclusion of shortstop prospect Deven Marrero, Nick Cafardo of the Boston Globe tweets.

Nick Swisher of the Indians is available in trade, tweets Jon Morosi of FOX Sports, but there has been minimal interest to date.

The Mariners could “circle back” to the Braves regarding Justin Upton if the team does not land free agent Melky Cabrera, tweets David O’Brien of the Atlanta Journal-Constitution. But Seattle is highly unlikely to sacrifice one of its prized young arms in a deal for Upton, he adds.

Reds pitcher and regular MLBTR reader Mike Leake keeps track of offseason trade whispers but tries not to worry about them, Mark Sheldon of MLB.com writes. “I’m curious. I check MLB Trade Rumors every day just to see what’s new,” says Leake, a potential trade candidate this winter. “There’s nothing you can do about it. You sit and wait and see if your name is thrown in a trade.” Leake notes that he would be happy to remain with the Reds, but would be understanding if they traded him.

If the Red Sox decide to deal Allen Craig, there will be interest despite his poor 2014 season, Nick Cafardo of the Boston Globe writes. The Marlins and Brewers have had interest in the past, and one evaluator expresses confidence that Craig’s performance last season was derailed by injuries and not by a steep decline in ability.

Also from Cafardo, Francisco Liriano would be a good fit in either the NL or AL, but teams are concerned about giving him more than a three-year deal since he’s never been an innings-eater. The Pirates remain interested in retaining him but not on a four-year contract. Some executives feel the “tipping point” of Liriano’s market will be if at least one team is willing to give that fourth year, ESPN’s Buster Olney tweets.

Justin Masterson has received a lot of interest but no actual offers yet, Fangraphs’ David Laurila reports. Laurila suggested in a recent column that Masterson could be a good candidate to be converted to relief pitching, though no teams have approached him with that idea and Masterson wouldn’t be interested if they did.

Also from Laurila’s piece, he talks to Burke Badenhop and the righty reliever said he felt he improved his free agent stock by posting strong numbers against left-handed batters in 2014.

Ichiro Suzuki‘s market is “not hot,” agent John Boggs tells Joel Sherman of the New York Post (Twitter link). Boggs is trying to push his client’s ability to play all three outfield spots and a bat that delivered a .284 average in 2014, hoping that teams won’t shy away because Ichiro is entering his age-41 season.

It would be surprising if the Rockies pulled off a blockbuster deal involving Troy Tulowitzki or Carlos Gonzalez during the Winter Meetings, Patrick Saunders of the Denver Post writes. “If I was a betting man, I sure wouldn’t put down money on a trade,” a Major League executive tells Saunders. The likeliest scenario is that neither player is traded (if at all) until they’ve proven they’re healthy.

Rival GMs tell tell Heyman that the Angels have made left-hander C.J. Wilson available, causing some to wonder if they might be trying to set up a run at a bigger pitcher via free agency or trade. The Angels have suggested they aren’t inclined to eat any of his $18MM annual salary and it’s pretty hard to see a deal coming together if they stick to that position. If they’re able to move Wilson, however, that could open the door for the likes of James Shields or Max Scherzer.

People familiar with Troy Tulowitzki‘s thinking believe that he’d only have interest in leaving the Rockies for about a half-dozen clubs, writes Heyman. That list is believed to include the Yankees (who filled their shortstop need last week), Dodgers, Angels, Giants, possibly the Cardinals, and one or two others. Still, owner Dick Monfort has suggested to inquiring teams that 30-year-old is not available.

The Braves have interest in Stephen Drew as a possibility at second base, according to Heyman. The Yankees, Mets and A’s are among other teams that have been tied to the 31-year-old, though the Bombers now seem less likely after acquiring Didi Gregorius.

With the Winter Meetings just a week away, MLB.com’s Anthony Castrovince names the top ten Hot Stove storylines heading into December. How the top-tier starting pitcher market shakes out heads the list, according to Castrovince, who notes the trade market for the likes of Cole Hamels, Jordan Zimmermann, and Jeff Samardzija will heat up once free agents Jon Lester and Max Scherzer sign. Among Castrovince’s other top headlines this month are whether the Braves trade Justin Upton and how the Red Sox and Dodgers deal with their surplus of outfielders.

The market for Kendrys Morales has been quiet to date with only the Indiansbeing linked to the free agent DH. CBSSports.com’s Jon Heyman tweets, besides Cleveland, the Rangers and Royals are also taking a look at Morales while the Mariners and Blue Jays are possibilities, as well.

Left-handed starter Andrew Albers recently became a free agent and has drawn interest from a number of big league clubs, an industry source told Ben Nicholson-Smith of Sportsnet. Albers became a free agent when South Korea’s Hanwha Eagles declined the 2015 option on his one-year deal. The Canadian pitched to a 5.84 ERA in 146 1/3 innings, though he did make 27 starts and led his team with 102 strikeouts. BN-S writes Albers appears to be seeking a split contract with incentives.

The Yankees called the Phillies to ask about the availability of Jimmy Rollins, reports ESPN’s Jayson Stark, but the asking price was deemed too high and the Bombers have since moved on (AllTwitterlinks). GM Ruben Amaro Jr. wouldn’t comment to Stark on the Yankees’ interest, but he tells Stark that Rollins is still one of the best shortstops in baseball and would therefore want a lot in return. Amaro adds that Rollins would be “very hard to replace” and is someone the Phillies want on their team. According to Stark, Rollins was never even approached by the team to ask if he would waive his no-trade clause to accept a trade to New York. Throwing even more cold water on the idea of a match, Stark reports (Twitterlinks) that the Yankees were offering only a “utility player” and that Rollins was not interested in playing in New York.

Here are some more notes pertaining to shortstops from around the league…

Andy Martino of the New York Daily News reports that while the thought of Troy Tulowitzki heading to the Yankees in a trade has long been considered a long shot, there are “recent, strong indications” that there’s absolutely no chance of such a trade. The Yankees are showing a real reluctance to take on another significant contract, and the six-year, $114 commitment Tulowitzki has remaining has no appeal.

Not only that, Martino hears from executives with interested teams that over the past two weeks, the Rockies have given the impression that Tulowitzki is simply unavailable.

The Dodgers are in the market for a stopgap to serve as a bridge to top prospect Corey Seager, reports MLB.com’s Ken Gurnick. The team feels that while whoever mans shortstop for them in 2015 won’t have the offensive talent of Hanley Ramirez, he will provide a marked defensive difference that offsets some loss of offense. Dodgers president of baseball operations Andrew Friedman and several Dodgers decision-makers watched Seager in the Arizona Fall League, and Friedman disagreed with scouts who feel that Seager will have to move to third base. Said Friedman: “I’m convinced that I would not move him off shortstop right now — his hands work really well, and we have a number of guys who think he has a real chance to stick there.”

In a video blog, ESPN’s Buster Olney notes that while three big-market teams — the Yankees, Mets and Dodgers — have a need at shortstop, the perception among executives is that there just isn’t much to be had. Executives feel that they could “absolutely” call the Mariners about Brad Miller, says Olney, but he’s been inconsistent at the plate. Stephen Drew hasn’t hit consistently over the past three seasons, either. Rollins has 10-and-5 rights and hasn’t given an inclination that he wants to approve a trade. And free agent Jed Lowrie is viewed by many teams as more of a second baseman than a shortstop.

Diamondbacks chief baseball officer Tony La Russa says he has hired Ed Lewis to take charge of the team’s analytical department, Brian Costa of the Wall Street Journal reports on Twitter. Lewis is an old friend of La Russa’s who does stock market analytical work, the head D’backs baseball man tells Costa. The question whether and how the Arizona ballclub would incorporate analytics into its operations has been a topic of interest since even before La Russa’s hiring, and it will be interesting to see what this latest front office addition means for the team’s intentions.

Here are a few more stray notes from the National League:

The Mets do not have any near-term intentions to approach second baseman Daniel Murphy about a contract extension, GM Sandy Alderson tells ESPNNewYork.com’s Adam Rubin. At the same time, the team is “reluctant” to deal him away at present, said Alderson. That could change, of course, if the club adds a new shortstop or otherwise adds offense, per the report.

Rockies GM Jeff Bridich says that deciding whether to deal stars Troy Tulowitzki and Carlos Gonzalez is “not just a casual type of process” for the club, ESPN.com’s Jerry Crasnick reports. Calling them “marquee” players, Bridich said it could be that other teams will not be willing to give up a haul that meets that lofty standard given both players’ injury issues. “We may or may not find out in the coming weeks,” he said. “Nothing of substance has taken place, so here we are.”

The Cardinals have “payroll muscle” at their disposal, GM John Mozeliak tells Derrick Goold of the St. Louis Post-Dispatch. Though the team has no intentions of spending its money just to put it to use, Mozeliak says it will do so in the right circumstances: “You’re definitely right in the assessment that we do have resources. If adding a year or adding a higher [average salary] means a deal, yes, we’re capable of doing that as long as it stays within the parameters of being rational.”

Deciding to deal a high-performing veteran is a difficult decision in many circumstances, none more so than for a team that intends to contend. That is the strategic choice facing the Nationals, who have several top players entering their final year of team control. As I noted about ten days ago in my offseason outlook for the Nats, the concept of a trade (most likely involving Zimmermann) has to at least be entertained, particularly if a young middle infielder was part of the return, and GM Mike Rizzo sounds willing to consider anything. Adam Kilgore of the Washington Post argues, quite validly, that this is not the time to be viewing the pitcher as an asset to be optimally leveraged, but rather an opportunity to push for the present (comfortable with the knowledge that a qualifying offer would still be available). Drew Fairservice of Fangraphs, meanwhile, proposes that the Nats should move the righty as a means not only of setting up for the future but also possibly addressing present needs (namely, second base).

A Mets trade for Rockies shortstop Troy Tulowitzki is “not happening,” a source tells Adam Rubin of ESPNNewYork.com. Rubin says such a move is not on the Mets’ radar due to the $120MM owed to Tulo through 2020, as well as the prospect cost of “two or three blue-chippers.” More from Rubin:

The Mets spoke with the Phillies about acquiring Jimmy Rollins, writes Rubin. Rubin adds, “The pursuit since has been dismissed because Rollins does not want to leave Philadelphia.”

The Mets are unenthusiastic about the available free agent shortstops, and plan to go the trade route to fill the position. The Diamondbacks, Mariners, White Sox, and Cubs are viewed as viable trade partners. Andy Martino of the New York Daily News says “it has been difficult, if not impossible” for the Mets and Cubs to agree on the value of Starlin Castro. Meanwhile, Martino says Alexei Ramirez of the White Sox only emerged as a possibility within the past week. Martino’s earlyread has the White Sox seeking the Mets’ top young starters and the Mets pitching their veterans.

If the Mets are unable to acquire a shortstop, or go with a defense-first type like Didi Gregorius, they are likely to retain second baseman Daniel Murphy, writes Rubin. If they get a shortstop who can hit, Murphy is more likely to be dealt if the Mets get a sufficient offer. Rubin expects the Mets to wait on Murphy until after resolving their shortstop situation.

The Mets seek a veteran lefty reliever to complement Josh Edgin in their bullpen. They are also seeking a backup infielder, unless Wilmer Flores is bumped to that role.

7:50pm: Rockies GM Jeff Bridich says that he’s had congratulatory and “what-are-you-looking-for” types of chats with the Mets, but no talks about Tulowitzki, MLB.com’s Thomas Harding reports. A source tells Patrick Saunders of the Denver Post that the two sides haven’t discussed the star shortstop, though the Mets could be discussing Tulowitzki internally. (Both links are to Twitter.)

3:43pm: The Mets just announced a two-year deal for Michael Cuddyer, but Jeff Passan of Yahoo Sports reports that he isn’t the only significant right-handed bat that has the team’s eye. The Mets have had recent discussions with the Rockies about shortstop Troy Tulowitzki, Passan tweets. While they fear that they cannot afford to add him, the two sides are talking. Newsday’s Marc Carig spoke to a source who characterized the talks as “due diligence” at this point (Twitter link).

A move for Tulowitzki would be expensive both financially and in terms of prospects, but the Mets do have a large stockpile of the type of young pitching which the Rockies covet. Noah Syndergaard, Zack Wheeler, Matt Harvey, Jacob deGrom and Rafael Montero all offer varying degrees of upside, and none have even reached arbitration to this point. (Syndergaard has yet to even reach the Majors.) Jon Niese is on an affordable contract, and Dillon Gee has yet to become overly expensive.

While it’s a lot to read into the situation at this time, a Tulowitzki acquisition would mean doubling down on a pair of injury-prone right-handed bats, as he and Cuddyer have both struggled to stay on the field in recent seasons. Tulowitzki is owed $20MM annually through 2019, plus a $14MM salary in 2020 and at least the $4MM buyout of his $15MM club option for the 2021 season. That adds up to a sum of $118MM over the next six years, so it’s not hard to see why the club isn’t certain it can afford to acquire him.

Still, the Mets are better positioned than most clubs to take on a long-term commitment, at least in terms of the other long-term pacts already on the books. David Wright‘s extension was front-loaded, and $20MM salary drops to $15MM in 2019 and $12MM in 2020. That contract is the only one on the books for the Mets beyond 2017, though Curtis Granderson will earn $16MM in each of the next two seasons and $15MM in 2017.

While the likelihood of a deal remains rather slight, and neither player is being shopped around, the report does indicate that Colorado is much more open to moving one of its stars than it had been previously. Notably, Rosenthal says that the Rockies are telling clubs that they will not accept a return that does not provide fair value for the healthy production levels of both players.

Needless to say, there is a large gap between a theoretical willingness to trade a player and a realistic chance of a deal getting done. In this case, that divide may be wider than usual. While Tulowitzki is arguably the very best shortstop in baseball, he has missed long stretches of time in recent years with hip, groin, and wrist surgeries, along with various other maladies. And he is due $20MM per year from 2015-2019, plus $14MM in 2020 and a $4MM buyout in 2021.

Much the same story holds for Gonzalez, who has had five-win seasons but had both knee and finger surgery last year. Then there is the fact that he put up just a .238/.292/.431 batting line when he was in the lineup last year, a fall-off that can in large part be pinned on his health issues but which nevertheless must be considered. Gonzalez is owed $53MM over the next three seasons, a steal if he’s healthy but a big problem if he is not.
